SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 612,310, dated October11, 1898. Application filed November 2S, 1896. Serial No. 613,223. (Nomodel.)

T0 all whom it may concern.-

Beit known that I, .IULIUs W. CRIGLER, a citizen of the United States,and a resident of Bloomington, in the county of McLean and State ofIllinois, have invented certain new and useful Improvements in AutomaticSash- Locks; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an improved lock for locking a window-sash, soas to prevent it from being raised without the insertion of a key forretracting a bolt which engages with a perforated metal plate or stripsecured to the side rail of the window-frame.

The invention has for its object to simplify the construction of thelock, so that it may be produced at a comparatively small cost, and alsoimprove it, whereby the sash will be rigidly held and prevented fromrattling, and whereby, also, additional security is attained against thesash being pried open by burglars or other unauthorized persons.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective View of aportion of a window frame and sash, showing my invention appliedthereto, part of the sash being broken away to show the perforated stripsecured to the frame. Fig. 2 is an elevation of the lock, the face-platebeing removed. Fig. 3 is a front view of the lock. Fig. 4 is aperspective view of the face-plate, looking from the inner side. Fig. 5is a horizontal section of the lock complete on the line x Fig. 2. Fig.6 is a perspective view of the perforated strip.

In the said drawings the reference-numeral 1 designates a window-frame,and 2 a windowsash, of any ordinary or suitable construction. One of theside rails of the said frame is formed with a vertical groove 3, to theedges of which is secured a metal plate or strip 4, formed with a numberof rectangular openings or perforations 5 to receive the bifurcated ordouble bolt hereinafter described.

The numeral 6 designates a lock adapted to be mortised in one of theside rails of the sash and secured in place by means of screws 7,passing through the front rim S of the lockcase.

The numeral 9 designates the back of the lock-case, consisting of arectangular plate provided with a rim IO at the top, bottom, and rearsides. v The front of this plate is provided with a rim which extendsabove and below the same and is formed with holes for the passage of thefastening-screws 7 before referred to. Near its lower end said front rimis cut away or formed with a rectangular opening for the passage of thebifurcated end of the bolt 13. This bolt consists of a rectangular metalbar or plate provided at its front with a central tapering recess 14,forming two wedge-shaped lugs 15. The outer ends of these lugs are ofsmaller size than the openings 5, so as to readily engage with the samewhen the bolt is shot; but they gradually increase in size, so that attheir junction with the bolt they are larger than the said openings. Bythis construction when the bolt is shot to lock the sash the springhereinafter described will force the lugs through the openings in thestrip, so that they will tightly bind against the upper and lower sidesof the openings, exerting a continuous spring-pressure, and therebyprevent rattling of the sash. In other words, no matter whether the sashts snugly in the frame or not the lugs, owing to their wedge shape, willalways be forced tightly into -the ,openings in the strip, the groove inthe rear of the latter allowing them to be projected sufficientlythrough the openings to make close contact with the sides of the latter.

At the rear or inner end the bolt is provided with a flange or a rib 16,with which engages the bit of a key to withdraw or retract it.

The numeral 16a designates a partition secured to the back plate andserves as a guide to hold the bolt in position, and is cut away at itsrear end to permit the end of a spring 17 to bear against the bolt andforce it outward.

The numeral 1S designates the cover-plate of the lock, formed with akeyhole 19, and is provided with a hole 2O for the passage of a screw,by which it is secured to a boss 2l on the back plate. The outer end ofsaid cover IOO plate is provided With a tongue 23, Which is bentinwardly and then rearwardly, forming a flange 24, to which is secured arectangular plate 25, which closes the opening in the front riin of thelock.

In use when the sash is lowered the ltapering lugs at the front end ofthe bolt will engage with the apertures additional strength or securityis given to the device against prying open of the sash.

Having thus fully described my invention, what I claim is Thecombination of a double pointed spring-actuated V-shaped bolt end with agage with the apertures in the plate or strip secured totheWindoW-frame, and thus prevent the sash from being raised. By reasonof the taper given to said lugs they Will it tightly in the apertures,and thus securely hold the sash against rattling. To raise the sash, thekey is inserted in the lock and turned so as to retract the bolt. Whenraised to any position desired, the bolt will engage with the aperturesin the plate and hold the sash in such raised or adjusted position.

By forming the bolt with two lugs to enkeeper having a series of holesto receive the points of the bolts, the stay between each pair of holesbeing narrow enough to be straddled by the points of said bolts,substantially as described.

In testimony that I claim the foregoing as my own I have hereunto afxedmy signature in presence of two Witnesses.

JULIUS W. CRIGLER.
